If and when you manage to survive the night defense in Chaos Squad, you’re up for a reward. Your base score from kills, goals, and other accomplishments will be multiplied by your Chaos level, with additional multipliers gained from any of the optional challenges you were able to accomplish along the way. The more of these you’re able to put together, the more points you’ll get.
Depending on your final score, you’ll get up to five “spinners,” each of which generates a random award, such as cash, Overcharge, or other bonuses. The score threshold for the last spinners may seem impossible to reach at first, but as you level your weapons and Overdrives, and learn the missions, they come into reach.
